133 Clock CPU on a 66MHz system?

For starters, the two probably have a different number of pins. And, no, it
will not work.

Can this be done from the BIOS too? What if the BIOS dates back too
far?

It would be nice if you supplied details. Otherwise
everyone is wasting their time guessing.

Sorry, but that is misleading. To support the new CPU the Front Side Bus
would have to be set to 133 instead of 66, which would require PC133 memory.
Also voltage for CPU is different. VERY unlikely if motherboard made for 66
FSB.

Sorry about the lacking details:
Current: Intel Celeron 466MHz Socket 370 66Mhz clock
Would like: Intel Pentium 3 1000MHz Socket 370 133 mhz clock

Heh, this is like pulling teeth. Mind telling us about your
motherboard make, model, and hopefully chipset? Do you have
PC133 memory or only 66MHz or PC100?

The P3 has a locked multiplier, so if your board supported
133MHz FSB you'd set it to that - if it didn't do so
automatically which it might. However, some boards of the
Celeron 466MHz era did not support 133MHz FSB and even some
that did, did not support Coppermine CPUs as your P3 is,
rather they only supported up to Mendocino Celeron (which
stopped at 533MHz), Deschutes P2 (stopped at 450MHz, IIRC)
and (forget the core name, P3 up to 650MHz in slot 1
format). In this latter case, you might be able to use a
slotket adapter (if it's slot 1) or pin-adapter for socket
370 adaptation from the Mendocino Celeron and Deschutes.

Now if you provide all the info as asked we can ignore all
info above and have a definite determination (unless the
board is some generic with no info available).

In the worst case, if it did not support Coppermine P3 AND
it did not support 100 or 133MHz FSB, an adapter would allow
the P3 to run at 500MHz which is not even worth the time to
hunt down the adapter. If the board supported 100Mhz FSB
then the P3's multiplier of 7.5X would allow 750MHz which
would be worth the adapter cost, "maybe", depending on the
use. 750MHz worth of P3 with 256MB of memory is about the
bare minimum that I'd consider reasonable for light-use
system running WinXP (or Win2k, so much the better). It
would make a decent fileserver, provided you added a
controller card for support of larger and faster PATA or
SATA interface drives.

It sounded to me that the OP was referring to a processor with a
main CPU speed of 133MHz, not bus speed. If this is an Intel
processor that would mean that it must be an original Pentium since
the 486 went up to 100MHz and the PPro started at 150MHz. That
would indeed imply a 66MHz bus speed.

In addition, chips of this era don't really have an FSB in the
technical sense, since they lack a backside bus - introduced in
the PPro.

I have done more research and the chipset is Intel 440ZX/100. The
current CPU is a Celeron (Mendocino) 466MHz (Socket 370). The CPU I
would like to put in is a Pentium 3 SL52R (Coppermine) 1000MHz (Socket
370).

Thanks

Which CPUs and mainboards are you talking about?
Please be more clear while asking questions to a newsgroup

It's asus but in a retail HP Pavilion so off hand i can't tell you
what model board.

I made some tests with Slot 1 CPUs and mainboards, which are very similar to
your ones.
I tried to use a PIII 500MHz 100MHz FSB Coppermine Slot1 on a very old AT
Slot1
mainboard from Lucky Star model 6LX2, designed for using only 66MHz.
The whole thing seemed dead, it only works with 66MHz, but i don't know if
it is like your case.
Which brand\model is your motherboard?

You have to look at the manual to see the clock speeds you can use on a
motherboard. If you don't have it sometimes you can find it in PDF form
Online but since its an obsolete system they might not bother to keep
copies no their website.

At the risk of seeming like an ass, I recommend you quit
replying to these very old posts. For example the one
you've replied to was posted in June. There is no
reasonable expectation anyone would have waited around for
3 months to receive your reply, they would have fixed the
problem or moved on by now.

IMO, your efforts are mostly wasted if you aren't replying
in a timely manner to current posts (a few days to a week
old, IOW) rather than those several weeks or months old.
